Definitions
- equation (6) empirically as a constant. It is a difficult process to determine the convergence
- the convergence of the smart antenna in the present invention can be verified through examining equation (9).
- the update weight vector can be rewritten as
- the adaptive convergence algorithms as in the present invention perform better in both views of convergence speed and the mean square error at a steady state.
